输入一个字节内的数（0~255）和移动位数。输出移位结果（要求循环移位）提示:系统自带的移位都是非循环的

unsigned char number = 0;

    int offset = 0;

    unsigned char left = 0;

    unsigned char right = 0;

    printf("输入一个字节内的数（0~255）和移动位数:\n");

    scanf("%d%d", &number, &offset);

    left = number << offset;

    right = number >> (8 - offset);

    printf("%d循环移%d位后为%d\n", number, offset, left | right);
